Every room is different. Every ear is different. Every speaker is different. Nobody can answer your question. Broad brush statement is, a mix of absorption and diffusion work best. Look for a decay time around 250 or so.

Hey all,
I have 9 foot ceilings and I sit in a 9 foot equilateral triangle with my speakers. Do I need to treat the ceiling? Absorption or defraction? I'm trying to get a deeper more 3D soundstage.Speakers are 46" from the front wall which is treated with absorption and defraction.
Thanks!
